As a part of the humid Southeast, North Carolina’s climate, topography, soils, cropping systems, and water sources require special consideration when considering and implementing a subsurface drip irrigation (SDI) system. This publication is not a step-by-step design manual, but it will help you in the design process of an SDI system appropriate to North Carolina.
Subsurface drip irrigation (SDI) is the practice of installing drip irrigation below the ground. SDI may be used below planting and tillage operations even in standard row-crop production systems. This publication is the first in a series that examines how North Carolina growers can use the technology.
